COVER FOR OiL-oups.

SPECIFICATION forming part of Letters Patent No. 314,638l dated March3l, 1885.

Application filed December 22, 1884.

To @ZZ whom imag concern:

Be it known that 1, JOHN E. ZIMMERMAN,

a citizen of the United States, residing at Springfield, in the countyof Clark and State of Ohio, have invented a new and useful Improvementin Covers for Oil-Oups, of which the following is a specification,reference being had to the accompanying drawings.

This invention relates to covers for Oilcups; te and it has for itsobject to provide an im- "proved valve for the same which will open toallow the free passage of oil and then automatically close the openingto the cup, and thus prevent the admission of dust, dirt, and

i 5 other foreign matter thereto.

To this end the said invention consists in certain details ofconstruction and combination of parts, as hereinafter set forth, andparticularly pointed out in the claims.

In the accompanying `a perspective view of my improved cover, showingthe top of the oil-cup. Fig. 2 is vertical longitudinal section of thesaine. Fig. 3 is a detail view of the cover with the 2 5 parts detached.Fig. is a horizontal section on thel line x 00, Fig. 2. Fig. 5 is aperspective view of the cap or cover separated from the cup.

Like letters of reference are used to indicate 3o corresponding parts inthe several figures.

Referring to the drawings, A designates the oilcup cap or cover arrangedto close the opening in the top of the oil-cup B. This cap or cover A ispreferably formed of one piece of metal, and is provided with an annularflange,

C, near its center, which extends outwardly,

as shown, the portion below the fiange being exteriorly threaded at D.Above the flange the cap or cover is formed with a hexagonal face orprojection, E, to receive a wrench or similar instrument in screwing itin place to the cup. rIhe cap or @over A is made hollow, its interiorwalls having vertical ribs or guides F, preferably four in number, whichextend from the upper to the lower end, the spaces G between the ribsforming passages for the oil. The closed ends of the cap or cover areeach provided with an `opening communicating with a annular ange orprojection,

(No model.)

Hin the top being larger in diameter than 5o the opening Iin thebottom.. 5

Jv designates the valve-stem, (shown in detail, Fig. 3,) having itswalls concaved, recessed, or hollowed out at K, for the passage oftheoil, and provided with a valve, L, at its lower end arranged to fit inits seat in the opening I. The sides of the valve are cut away at a tocorrespond with the recessed walls of the stem, so as to allow theadmission of oil from the cup to the cover when the 6o stem isdepressed. The upper end of the stem is provided with a disk, M, whichmay be made detachable, as desired, said disk closing the opening H inthe upper end of the cap or cover, and in its normal position fittingflush therewith.

N designates a coiled spring encircling the valve stem, and having oneend pressing drawings, Figure 1 is i against the disk M, and the otherend against the lower end of the cap or cover around an 7o N', thelatter encircling the opening I.

The operation and advantages of my invention will be readily understoodfroi'nthe foregoing description, taken 'in connection with 75 theannexed drawings. The cup or cover is applied in position, as shown inFigs. 1 and 2, the threaded extension D screwing into the threaded mouthin the top of the oil-cup B, and the flange O resting over the upperedge SO of the latter, a wrench or similar instrument engaging with thehexagonal projection E for the purpose of fitting the cap in place, asstated. A

In operation, by depressing the disk M 8 5 the valve-stem works downwardagainst the pressure of the spring until the valve is withdrawn from itsseat to allow the admission of oil to the cap or cover, the oil flowingout through the opening H. V'Vhen pressure is re- 9o lieved, the springexerts its power and forces the valve-stem to its normal position,thedisk closing the opening at the top and fitting ush, as shown, and thevalve resting in its seat and closing the opening I at the bottom. 9 5

The ribs or guides F serve to guide the ascent and descent of thevalve-stem and hold the spring in place, the spaces between the theinterior of the cup,'the opening ribs permitting the free passage of oilthrough the cap. The flange or projection N at the lower end of caparound the opening I serves to keep the spring in place and preventdislodgment thereof.

As will be seen, when the valve is pushed away from the opening I, theoil is allowed ingress through the cut-away portion a and the-recessedwalls of the valve-stem.

My improved oil-cup cover may be applied to all sizes and forms ofoil-cups. It is simple in construction, inexpensive to manufacture,efficient in operation, and convenient in use. By means of the same theoil will be allowed free passage from the cup by the action of thevalve, the latter being automatic in operation, so as to close andexclude dust, dirt, and other foreign matter from passing into the cup.

Having described my invention, I claiml. The combination,with theoil-cup provided with a threaded opening, of the cap or cover having athreaded portion to fit thebpening, and a hexagonal face or projectionto receive a wrench in turning the cap into place, as set forth. p

2. The combination, with the oil-cup provided with a threaded opening,of the cap or cover 'having a threaded portion to screw into theopening, a hexagonal face or projection to receive a wrench in turningthe cap into its place, and an annular flange between the threadedportion and the face or projection, as and for the purpose set forth.

3. The herein-described oil-cup cover having a spring-pressed valvewhich will open by pressing inward to allow the free passage of oil andthen automatically close outward to exclude the admission of foreignmatter, as set forth. e

4. An oil-cup cover or cap made hollow and having an opening at theupper and lower ends and avertically-movable automatic valve to open orclose said openings, as set forth.

5. An oil-cup cap or cover made hollow and having an opening at theupper and lower ends, ribs or guides extending along the interior wallsof the cap, and a vertically-movable valve, arranged and operating asset forth.

6. An oil-cup cover or cap made hollow and having an opening at each endfitting normally iiush with the opening, a valve-stem moving therein, avalve at one end of the stem for closing one of the openings, and a diskat the other end, as set forth.

7. An oil-cup cover or cap made hollow and having an opening at eachend, a valve-stem moving therein and having its walls concaved orhollowed out, avalve at one end of the stem having its sides cut away,as described, and a disk at the opposite end, as set forth.

8. An oil-cup cover or cap having an opening at each end, a valve-stemmoving therein, a valve at one end of the stem, a disk at the oppositeend, and a spring bearing against the disk and the end ofthe cap orcover, as set forth.

9. yAu oil-cup cover or cap made hollow and having an opening at eachend, ribs or guides extending along the interior walls of the said capand forming spaces between each rib, a valve-stem moving in the cap, avalve at one end of the stem, a disk at the other end, and recessesformed in the sides of the valve-stem, the sides of the valve being cutaway to correspond with the recesses, as set forth.

10. An oil-cup cover or cap made hollow and having an opening at eachend, ribs or guides extending along the interior walls of the said cap,a valve-stem provided with a valve at one end and a disk at the other, aspring bearing against the disk and one end of the cap or cover, and anannular iiange, around which the lower end of the spring lits, as setforth.

1l. An oil-cup cover having asprin'g-pressed valve-stem moving thereinand a disk at one end of the stem arranged to close the' eXitopening andto rest ush with the cover in its normal position, as set forth.

In testimony that I claim the foregoing as my own Ihave hereto affixedmy signature in presence of two witnesses.
